Toprammer is software for the TOP2049 universal programmer. As all programming algorithm logic is implemented in software, it does not support all the devices that the original "Topwin" Windows software supports. However, support for new chips can be added, if needed.

System# is a .NET library intended for the description of real-time embedded systems. It comes with a built-in simulator kernel and a code transformation engine that converts a design into synthesizable VHDL. The main focus is currently the development of FPGA designs. System# not only supports register-transfer-level (RTL) descriptions whose translation to VHDL is straightforward, but is also capable of converting clocked threads with wait statements to a synthesizable VHDL state machine. Furthermore, System# introduces synthesizable transaction-level modeling features. From a technological point of view, it uses reflection and assembly code (CIL) decompilation to reconstruct an abstract syntax tree (AST) from the system design. The AST conforms to SysDOM, a document object model for describing component-based reactive systems. An unparsing stage converts the AST to VHDL. The decompilation process can be instrumented in various ways by attribute-based programming. Furthermore, transformations of the AST itself are possible. This enables implementation of advanced features such as converting clocked threads to finite state machines.
